HENRY LEE PARKER AND ALTON EBENEZB COBB, 0F LOS ANGELES, CALIFO I- eCOMBINED REGULATING AND SHUT-OFF FAUCET.

Specification of Letters Patent.

Patented Feb. 19, 1918.

Application iled April 26, 1915. Serial No. 24,108.

To all whom t may concern:

Be it known that we, HENRY LEE PARKER and ALroN EBENEZER COBB, citizensof the United States, residing at Los Angeles, in the county of LosAngeles and State of California, have invented a new and useful CombinedRegulating and Shut-OE Faucet, of which the following is aspecification.

An object of the invention is to Provide a faucet which is applicablefor long and short connections and is adapted to be used as a wash-standfaucet, a hose bib, a shampoo wash-stand connection or a connection foruse in laboratory work, and which can be regulated to limit the volumeof liquid that will flow therethrough when the faucet is fully open.

An object is to provide a faucet in which the service valve can be cuton' from the service, so that said service valve may be removed,repaired and replaced without cut-- ting off the water supply at thestreet valve; also to provide for easy and Cheap repair.

An object of the invention to so construct a faucet that the same bcdyand nozzle can be used with a Fuller ball valve or compression valve asl(meas-ien may require.

Another ohiect is to make provision whereby a swivel hose attachment canbe conviently applied to the faucet.

Another object is to provide for conveniently molding the faucet body.

Other objects and advantages may appear from the subjoined detaildescription.

The invention is capable of being carried out in various ways.

The accompanying drawings illustrate the invention in the form atpresent deemed most desirable.

Figure 1 is an axial section of a fauci' constructed in accordance withthis invention ready for application as a hose-bib, either with a longor with a short connection. A compression valve is shown partly closedand the regulating valve is shown fully open.

Fig. 2 is an elevation partly in section of a faucet having a bodyidentical to that l"shown in Fig. 1, the same being supplied with aFuller ball valve and being mounted on a wash-stand, and connected witha swivel connection adapted to receive a hose for shampoo purposes. TheFuller ball valve is shown partly open and the regulating and cut-olivalve is shown partly closed:

The faucet body l `may be of any usual material such as brass,composition metal, galvanized cast-iron, etc., and is provided at itsinlet end 1with the attaching portion 2 having internal and externalthreads 3, 4. The inlet 5 may be circular or of any desired shape incross-section and leads to the valve chamber 6 surrounding aninternallythreaded barrel 7, forming an orice for mounting a valve stemand valve in said valve chamber. An internal web 8 having a port 9therethrough divides the interior of the faucet into the two valvechambers 6 and 10, which chambers are provided with orifices 11, 12 toreceive the valve stem bushings 13, 14 respectively that are suitablymounted in said orifices 11, 12, to carry valve stems 15, 16, that arearranged co-axially` with, and on opposite sides of, the port 9, areprovided with threaded portions 17, 13, screwed into the bushings whichare threaded as nuts. The bushing nut 13 is shown provided with anannular channel 19 to receive the annular gland 20 to hold suitablepacking 21 in place. The bushing 14 is of a different type, being heldin place by a bonnet nut 22 screwed onto the threaded boss 23 externallysurrounding the orifice 12 and projecting from the body 1 of the faucet.Said bonnet nut 22 1s provided with a screwthreaded portion 24 toreceive a gland 25 compressing the packing 21 around the valve stem 16.The second valve chamber 10 communicates with an outlet 26 that isinternally threaded to receive the reduced end 27 of a detachable bibnozzle 28 that may be externally and internally threaded as shown inFig. 1, for connection to a hose coupling or nipple, or may be threadedeither internally or externally only; the latter form being Shown inFig. 2. Said bib nozzle 28 is preferably provided with an unthreadedneck 29 between the main body 30 and an enlarged threaded tip portion 31of the nozzle. Upon said threaded portion 31, a

gland 32 may be screwed to compress packing`33 around a tube 34, whichis-of like -straight cylindrical form at both ends and comprises twolimbs united centrally at a common nipple 35 to' receive a hose, notshown, and being rotatable at the joints thus formed. l/Vhen thecylindrical ends of the xture as at 34 are connected with the hot andcold water faucets of a wash-stand 36, the installation is complete forfurnishing to the central nipple 35 and the hose, not

shown, hot, cold and variously tempered water. f

The port 9 is provided with two flat valve seats 37,38. In order thatthe flow of water can be regulated a Hat-faced compression valve 39 isprovided in the first valve chamber 6 on the end of the valve stem' 15to close against the valve seat 37 on the inlet side of the port 9. Saidvalve stem 15 is provided with a slot 40 to admit a, screw-drlver, notshown, to adjust the, valve 39 to any position in the valve chamber 6desired to determine the exact amount of water that can iow through thefaucet when the flat-faced compression valve 41 is fully open.

The bib nozzle is provided with a guide 42 and a valve seat 43; and inFig. 2 a Fullerball valve 44 is mounted on a Fuller valve stem 45 and isprovided with a guiderod 46, the same being mounted'in place as shown tocontrol the flow of liquid through the valve chamber 10. Said valvechamber is thus provided with two-valve seats, the produced axes ofwhich'intersect at right angles, so that the one fitting is adapted forinstallation alternatively with a compression valve or a Fuller valve.

The connection 47 between the valve 44 and crank 48 may be'of any commonwell-known construction.

The valve stem 45 is provided with an annular groove 50 in which a pin51 is driven through a hole 52 bored through the neckof the bushing 114,thus to hold the stem 45 in true position. y

By unscrewing the bib nozzle ready ac- 'cess is gained to the valve ballwhich ca be removed in an obvious way.

By mounting the valve stems in the detachable bushings 13, 14 the lifeof the faucet body isprolonged indefinitely, since Fuller ball the wearandtear-on the threads caused by opening `and closing the faucet doesnot a'ect the body of the faucet, and when the valve 41 and the threadson the valve stem 16 of the compression valve become worn it is simplynecessary to close the valve 39 and then unscrew the bonnet 22, detachthe faucet handle 49 from lthe valve stem, with draw the valve stem 16from the bonnet and gland, and discard the bushing valve and valve steminstead of throwing away the faucet body.

A faucet provided with two valve chambers; a port between'and incommunication with said valve chambers; said port having a fiat seat atits inlet and a fiat seat at its outlet; a flat-faced compression valveadapted to be adjusted to control the inlet to said port; a bib nozzledetachably connected to the outlet of thev faucet; said vdetachablenozzle having concentrically therein guiding means for a Fuller ballvalve stem and at its attached end a valve seat for said ball valve;said faucet thereby being adapted for use alternatively in connectionwith a fiat-faced compression vvalve for opening and closin the outletof said port or a Fuller ball va ve adapted to open and close upon thevalve seat in the nozzle, to contr'ol the ilowof liquid through saidfaucet.

In testimony whereof we havehereunto set our hands at Los Angeles,California, this 20th day of April, 1915.
